Make this as short as I can. I've made removing some water spots from a shower door and personal battle between me and the spots. I have tried over a dozen major acidic products and home remedies - NOTHING has worked. then I read someplace to just use baby oil; yes, baby oil. Well I tried and I'll be damned if it didn't look like it's worked miracles. Now I know it is not removing the hard water spots because nothing comes off on the rag. but it sure makes them disapear. Does anyone know what is going on? I suspect after a few days the spots will just come back again in all their glory.
